Hello there, I'm trying to set up the tracking for my keywords, as I've read it is key in order to know what words are converting and which should be taken out of the campaign. I'm trying to set up a little mySQL database where I can list each click towards the merchant, with a sub-id and other info (keyword that led to the site, time... etc). SO, the thing is I want to specify that sub-id in the link towards the merchant, so I can later on succesfully identify the sales and what click they came from. I'm with CJ and for every product my merchant offers I get an html code with something like this towards the end: (note x,y,z,w are numbers) <input type="hidden" name="pid" value="xxxxxxx"/> <input type="hidden" name="aid" value="yyyyyyy"/> <input type="hidden" name="cjsku" value="zzzzzz-zzzzz"/> <input type="hidden" name="url" value="http://www.merchant.com/bla-bla/?wmcp=cj&wmcid=feeds&wmckw=wwww-wwww-wwww"/> <input type="submit" value="Buy"/> That is a submit button with "Buy" that leads to a url like this: http://www.merchant.com/bla-bla/pro...&AID=YYYY&PID=XXXXXXX QUESTION: In order to track, wouldn't I need to make a call to that page with '&sub-id=zzz' at the very end? Example: http://www.merchant.com/bla-bla/pro...XXXX&sub-id=zzz As far as I know, I shouldnt touch AID and PID, and add sub-id with the corresponding number calculated with a little php script on my website. If what I said is correct, then I'm happy because it means I understood the basics . The thing is: How can add the sub-id if the merchant is not giving me a LINK to deep-link his product, but a FORM ("buy") with weird information on it? Maybe something like adding: <input type="hidden" name="sub-id" value="<? echo $sub-id; ?>"/> ??? They do offer text links, but in such a case i would need to adapt all products with a text link instead of the form. Or even use that textlink in the href of the pic of the product. --- I know I shouldn't launch my campaign until I set this up. And I'm stuck. A bit of guidance would be very appreciated!
